LG was a bit more enthusiastic in its statement, saying, “Never have, never will! We care what our customers think.” OK, then. Samsung was a bit more collected, noting that they use software tricks to adjust battery charging current and duration, but that they “do not reduce CPU performance through software updates over the lifecycles” of phones.

Here is Samsung’s full statement:

Samsung Electronics Co.,LTD.: Product quality has been and will always be Samsung Mobile’s top priority. We ensure extended battery life of Samsung mobile devices through multi-layer safety measures, which include software algorithms that govern the battery charging current and charging duration. We do not reduce CPU performance through software updates over the lifecycles of the phone.

So that’s four of the big dogs weighing in with confirmation that they don’t downgrade the performance of older phones in the way that Apple did because of aging batteries. Now we just need to hear from Google.
